Won't compile for ruby-2.0.0-p195

[fotanus]

It works well with ruby-2.0.0-rc2, but not with p195. I didn't dig deeper to see the problem, just switch back to 2.0.0-rc2 for now.

Here is the output:

user@app:~/sandbox/app$ gem install ferret

I have the same issue. However, it's worth noting that it installs successfully on Mac OSX 10.8.4. Did you manage to solve the issue?

[fotanus]

@elhu not yet, sorry. The update was postpone, and with it, this issue. Let us know if you find the problem the solution.

[elhu]

@fotanus I tried installing ferret with the latest ruby release (p247), and it compiles again !

[fotanus]

@elhu great! Thanks for letting me know! Let's close this then.
